GF72.29-P-3007PP Automatic Raising/Lowering Power Windows, Function


Function requirements:
- No overvoltage or undervoltage
- C. 15 ON or C. 15R ON
- Power windows in synchronized state (for automatic raising)
- Function not disabled in variant coding
- Correct rotation direction of power window motor and
- Hall sensors not defective

Model 203.7 is not equipped with rear door control modules and power window motors.

Operation
The automatic raising/lowering function is performed by briefly pulling back or pushing forward a power window switch in the "close" or "open" direction beyond the first click-stop position.

Via corresponding:
- Left front door control module (N69/1)
- Right front door control module (N69/2)
- Left rear door control module (N69/3) and or
- Right rear door control module (N69/4)

the corresponding:
- Left front power window motor (M10/3)
- Right front power window motor (M10/4)
- Left rear power window motor (M10/5) and or
- Right rear power window motor (M10/6) are actuated.

The actuation remains active until it recognizes via position recognition that the window is completely closed or opened.

Automatic raising
The "automatic raising" function effects automatic window raising with excess force limitation (pinch protection) and can only be performed on synchronized windows. As long as no other button signals are detected, the window will be completely closed to the upper end stop position.
If the system detects that the rotation direction of the power window motor is incorrect or that a Hall sensor is defective for 12 rotations of the armature, automatic raising is immediately aborted.
Upon detecting an "incorrect rotation direction" or "defective Hall sensor" fault, or a desynchronized window, the system will respond to any continued request for "automatic raising" by actuating the "manual raising" function.

If the system recognizes the "manual raising" button function after having recognized the "automatic raising" button function and without first having detected the neutral position, the "automatic raising" function remains active.

Function abort
The "automatic raising" function is interrupted if:
- Function requirements are not satisfied
- An obstruction is detected
- Another switch position after neutral position is detected
- There is a response from the excess force limiter (obstruction sensor) Activation > 25 s and
- Zero point tolerance exceeded

Automatic lowering
The "automatic lowering" button function effects automatic window lowering and can be performed without synchronization. As long as no other button signals are detected, the window will be fully lowered to the lower end stop position.

Function abort
The "automatic lowering" function is aborted if:
- Function requirements are not satisfied
- Another switch position after neutral position is detected
- An obstruction is detected
- activation > 25 s and
- The maximum travel distance for synchronized windows is exceeded
